OrthoTest: common questions

What microcontroller does the OrthoTest use?

The OrthoTest is built around the RaspberryPi_Pico, from the RP2040/RP2350 family.

How big is the OrthoTest PCB?

The OrthoTest measures 233.7 × 127.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the OrthoTest?

244 components, from 9 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the OrthoTest design files?

From the extinct00/OrthoTest repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the OrthoTest design in my own project?

The repository has no license, so all rights stay with extinct00. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the OrthoTest without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
